Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, in particular to a quantitative casting mechanism for a magnesium ingot casting machine. Background Art

[0002] In the magnesium metal industry, 100g and 300g small magnesium ingots have always been cast in the factory. Mechanical casting has only been used in the past one or two years. There are three reasons for this. First, the weight deviation of small magnesium ingots is small, only a few dozen grams. The weight deviation of each mold of the casting machine is not easy to control and it is easy to exceed the standard. Second, the weight deviation of each small magnesium ingot cast by the same mold of the casting machine is not controlled. Third, it is difficult to preheat and keep the ladle warm. In addition, the casting tube needs to be preheated, which makes operation and control more difficult.

[0003] Chinese patent document CN218192518U discloses a double-disc fully automatic quantitative casting machine, including a casting disc frame and a casting tray. Both sides of the bottom of the casting disc frame are fixedly connected with side plates, and the inside of the side plates are provided with card plates. The inside of the side plates is provided with second springs at both ends of the card plates. The inside of both sides of the casting tray is provided with card slots matching the card plates. The side plates and the casting tray are connected through the card plates and card slots under the action of the second spring. The card plates, the second springs, and the card slots are provided in two groups, and the two groups of card plates, the second springs, and the card slots are symmetrically arranged with the casting tray as the center. The above-mentioned double-disc fully automatic quantitative casting machine has shortcomings. Although the device realizes quantitative casting, it has limitations. It is not suitable for the casting of 100g small magnesium ingots and 300g small magnesium ingots, which easily causes large casting deviations and low casting efficiency.

[0004] Therefore, in order to solve such problems, we proposed a quantitative casting mechanism for a magnesium ingot casting machine. Utility Model Content
